While sometimes I wish I could have trained in one dojo uder one master and had an easy time of it, my meandering has at least introduced me to a myriad of ways to do techniques (caused me a lot of trouble for a long time, in more ways than one). And while wandering, what I have noticed is that each 'group' has their own way, and if you show them another way they simply cannot do it and assume that it must be wrong, or at least it is too different to bother with. Accordingly, I find that I judge people not by their ability at what they can already do, which always looks pretty good, but by their ability to pick up new variations instantly, which, I find, they often cannot do.
